Letters Patent No. 112,149,

IMPROVEMENT IN HARROWS AND FIELD-ROLLERS.

The Schedule referred to in these Letters Patent and making part of thesame.

I, ABRAHAM S. KEAGY, of Harristown, in the county of Macon and State ofIllinois, have invented certain Im 'irovements in Sectional.ltevolving-IIarrow and 'l ield-Roller combined, of which the followingis a specification.

Nature and Objects of the I nccn ttoa.

My invention relates to a combination of sectional revolving-harrows andfield-rollers, and consists mainly in the construction and novelarrangement of devices whereby a number of revolving harrows andfield-rollers are combined in the same machine, and arranged to operateindependently of each other. Also, the manner in which the teeth in therevolving barrows are kept from clogging in heavy ground by teeth inthat portion of the horizontal frame in rear of the revolving barrows,and the manner in which the frame of the rollers is attached to theframe of the barrows so as to give the. frame an npward-and-downwardmotion.

Description of the Accompanying Drawing.

Figure 1 is a side elevation of a machine embodying my invention.

Figure 2 is a plan of the same.

Figure 3 is a vertical section thereof.

General Description.

A is the pole of the carriage.

B, the transverse beam, to which it is secured by tenon and mortise, andbraced by rods a a.

O designates the horizontal frame which passes around the barrows.

D represents a trough for conveying stones, trash, 8.70., out of thefield, and serving, also, as a seat for the driver.

The trough is supported at each end by standards a d. When necessary thetrough may be weighted to operate on hard soil.

E is a long rod extending from one end of the carriage to the other, andsecured to the sides of the frame 0, and to the bearing-pieces b bfastened to the beam B.

G G designate the revolving barrows, which are studded With barrow-teethg g, and rotated by the drawing of the machine.

Each of these revolving narrows arefixcd in a separate frame, composedof two side-pieces, H H, 0011- nccted together by the rod h at the top,and by the axle 7; of the barrow.

The side-pieces H H are right-angled, and the axle It is screwed firmlyinto each at the angular Joint.

1 The horizontal arms I I are pivoted to the transverse rod E, and theupright arms c c are expanded at their upper ends and abut under theseat or trough D, thereby serving to give the barrows even ness ofmovement on level ground and to prevent the trough from touching them.

The rear horizontal bar of the frame 0 is studded with teeth 1' i,curving downward, and serve to clean the teeth of the revolving .harrowsand to prevent them from clogging on heavy ground.

The frame 0 is braced with an arched .bar, X, bolted on the beam 13 andthe rear horizontal har ot' the frame 0.

L is a horizontal frame that passes around the rollers, and is pivotedto the frame 0 by means of transverse .rod .M passing through anextension of the frame O,horizontal frame L, and bearing-pieces b I),said bearing-pieces being attached to the rear horizontal bar of theframe 0, thus giving the frame L an npward-aud-downward motion.

0 O designate the rollers, which are operated in the same manner as theharrows, and for which a patent was granted to me April 5, L370, No.101,626.

This machine is designed to be drawn by a span of horses. Each section,being independent in its construction, does not interfere with theoperation of the others; and thus, while one of the barrows orrollersmay be passing over a large clod, stone, or other obstruction,the others will continue to operate on the level ground or in anydepression thereof.

The machine is easily turned, as in this operation the other harrow androller can reverse their motion.

The harrows can be removed and the rollers substituted when it isdesired to use the machine as a roller only.

The rear horizontal bar of the frame L serves as a scraper to detach thesoil from the rollers.

If it be desired to remove this bar further to the rear, scrapers may beattached to it for this purpose.

The axles It I; pass through boxes as a in the harrows and rollers,thereby securing strength and uniformity of worl The whole machine canbe taken to pieces and readily boxed for transportation.

Claims.

I claim as my invention- 1. The revolving harrow herein described,consisting of the sectional revolving barrows G. G, arranged to moveabreast of each other, but each having an independent upward or downwardmotion, as specified.

2. The revolving harrow herein described, having sectional harrows G G,turning upon independent axlcs I; It, screwed into the independentflames H 4. The combination of the rod M, frames C and H, connected tothe horizontal rod E by the arms T1, and rollers O O, substantially asdescribed.

I I, and provided with the trough or seat D, sub- ABRAHAM S. KEAGY.stantially as and for the purpose hereinhefore set I forth. Witnesses 3.The combination of the teeth M, frame 0, and OHARLEs I. HOUSUM, barrowsG G, substantially as described. Row. B. IVIOHEGAN.
